Roller Pinion Gear System

Product Type: Roller Pinion Systems

The Roller Pinion Gear System (RPG) is based on an innovative pinion consisting of bearing-supported rollers and a unique tooth profile.

This unique drive system provides very high positional accuracy, near-zero backlash, virtually no cumulative error, low-velocity ripple, unlimited length, very high speeds, high rigidity, low noise, low maintenance, corrosion resistance, long life, and 99% efficiency.

This opens up new machine design possibilities and provides the capability to achieve much higher levels of performance.

Full Gears with External Teeth

Roller Pinion gears with external teeth offer very high levels of rotary accuracy.

Roller Pinions are used with RPS rack and gear sets. The rollers are bearing supported for very low friction and long lives. Nickel plating on the body offers some corrosion resistance. The ISO9409 flanging makes reducer selection and pinion installation easier, provides a more rigid system, and allows the use of Nexen preloaders.
